There’s several variants of both Mother 1 and 2. There’s Mother 1 in Japanese, if I recall it has several localizations, including the official one “Earthbound Beginnings” which you can find on the Switch NES Online service; I understand a proper localized patch is the preferred path, but every time you google these things you get a different perspective.
There’s also several Mother 2/Earthbound ROM hacks and localization patches to consider.
